Is there a chance that I could retrieve it back? I just want to be sure, so I will not encounter any problem at all. thank you...

ok...do I have to do the same procedure on the first post if I want to change my theme again?

It depends, This is not actually for changing themes. This is used for upgrading your firmware. It just happened that the firmware you are upgrading to has a theme. You can use LG KM555 Utils for modifying your theme.
